SPECIFICATION forming m of Letters PatentNo. 633,870, dated September 2c, 1899.

Application filed March 21,1899. Serial No. 709,941.. on model.)

To'crlfi'zuhom it may concern:

Be it'known that I, CHARLES W. LYON, a citizen ofthe United States, residing in Philadelphia, Pennsylvania, have invented Improvements in Presses for Forming Picker Lug-Straps, of which the following is a specification.

My invention consistsof a press for-the manufacture or picker lug straps, such as shown and described in my Patent No. 620,469,

dated February 28,1899, the object of my invention being to retain the strap in its proper position in the outer die while the bent end of the strap is being subjected'to' the pressure of the inner die.

In the accompanying drawings, Figure 1 is, a perspective View of alug-strap. press constructed in accordance with my invention."

Fig. 2 is a longitudinal section of the same. Fig. 3 1s a sectional plan view on the line x at, Fig. 2; and Fig. at is a view illustrating a modified construction of part of the machine.

The press shown in the drawings comprises a base 1, with rounded socket 2 for the reception of the rounded end of the lug-strap and:

' an upwardly-projecting flange or side plate 3 for hearing against one side of said strap, a detachable .side plate 4: fittingbetween opposite end wings 5 of the press and bearing against the other side of the strap, said plate being acted upon by a earn 6, hung upon a pin 7, which is carried bysaidjwings 5. I

The inner die-block 8 is acted upon by a cam 9, hung upon a pin 10, carried by the upper ends. of the wings 5, and through a slot 11 in the upper portion of said inner die is free to move vertically a slide 12, having at its opposite ends plates 13, which act as end presser-plates for the strap, the slide 12 being depressed by means of a spring 14, inserted between the same and a plate 15, which closes the upper end of anopening formed in the die-block 8 for the reception of said spring. The die-block 8 and presser-plate a being removed from the press, the cemented strips of leather, with interposed filling-piece, which. are to form the lug-strap, are bent around the inner die 8, the end presser-plates 13 insurof the bent end of the strap, the full pressure of the inner die being concentrated against said bent end, owing to the fact that the opposite sides of the strap are so confined that they cannot expand laterally.

I have shown my invention as embodied in a single press 5 but it will'be evident that a number of presses maybe disposed side by side, a single shaft carrying all of the'cams 6 and another shaft carrying all of the-cams 9, so that each set of cams 6 or Q can be moved simultaneously.

The necessity for removing the side plate 7 4 from the press for the introduction of the inner'die Swith the strap upon it may be overcome by making the upper earn 9 removable, so that the die 8, with its strap, can be introduced vertically between the side plates 3 and 4, This may be done by slotting the wing-plates 5, as shown at 16 in Fig. 4, for

instance, so that the pivot-pin 10 can be slipped into and out of position.

Having thus described my invention, I claim and desire to secure by Letters Patentv 1. The combination-in a lug-strap press, of the base and side plates, one of which is-reportion of the rounded end of the lug-strap, a cam for moving the said side plate inward, a detachable inner die-block around which the strap can be bent before the block is placed in the press, and a cam for forcing said die-block down between'the side plates, substantially as specified.

2. 'The combination in a lug-strap press, of the baseand the side plates with the inner movable, said base forming a die for the outer block so as to center said strap thereon, subdie-block around which the strap can be bent, I name to this specification in the presence of the spring-actuated presser-slide on said intwo subscribing witnesses.

ner die-block adapted to bear against the r ends of at strep bent around the inner die- CHARLES Li W'itnesses:
